5Diketahui F(x) = 2x + 1 dan 9 (x) = 3-2x, mata (F.g)(x)=....A.-4x² + 4x +3B.x² + 4x +3C. - x²

tutadi

Jawab:

semoga membantu

Penjelasan dengan langkah-langkah:

f(x) = 2x + 1 dan g(x) = 3 - 2x

(f.g)(x) = (2x + 1) . (3 - 2x)

............ = -4x² + 4x + 3 (A)

A. -4x² + 4x + 3

------------------

$\mathbb \color{orange} \underbrace{PENYELESAIAN}$

$\underline{ \overline{ \boxed{ \bold{diketahui}}}}$

f(x) = 2x + 1
g(x) = 3 - 2x

$\\ \underline{ \overline{ \boxed{ \bold{ditanya}}}}$

(f . g)(x)

$\\ \underline{ \overline{ \boxed{ \bold{jawab}}}}$

$\begin{aligned} \sf (f \: . \: g)(x) &= \sf f(x) \: . \: g(x) \\ &= \sf (2x + 1)(3 - 2x) \\ &= \sf 6x - {4x}^{2} + 3 - 2x \\ &= \bold{ { - 4x}^{2} + 4x + 3 }\end{aligned}$

------------------

$\mathbb \color{red} \underbrace{KESIMPULAN}$

Jadi, hasil dari (f . g)(x) adalah -4x² + 4x + 3
